Just over a year ago, I read a great book, called "Quiet", by Susan Cain, all about 'the power of introverts'.
In another of the occasional examples that my employer seems to be popping up with recently of showing some encouraging signs in their approach to training and people development (see also this post, as well as a post or two that I will eventually get around to writing as follow up to that meeting and subsequent reading), I was sent a link the other day to a talk by Susan Cain.
It is 20 mins, but it is well worth a watch. I enjoyed it greatly - but then again, I would, wouldn't I, introvert that I am!
